Chris Muller uploaded a new version of Morphic to project The Trunk:
http://source.squeak.org/trunk/Morphic-cmm.453.mcz

==================== Summary ====================

Name: Morphic-cmm.453
Author: cmm
Time: 3 July 2010, 4:20:46.206 pm
UUID: ad89ffef-f10d-4ab5-853f-c2a12140ccd6
Ancestors: Morphic-cmm.452

Added "Auto Enclose" preference.  When true, typing an opening parenthesis, bracket or square-bracket will also add its corresponding closing character in front of the cursor.
